Forging

A very old metalworking process, traditionally carried out by a blacksmith with a hammer and anvil, and used to shape metal under compressive force. In modern industry, forging is carried out by powered presses or hammers. Metals are generally hot forged, but can also be cold forged. Because of the effect on grain flow, which is compressed to follow the part shape, forged components are generally strong and tough.
